Abstract: A method for probabilistic fatigue life prediction using nondestructive testing data considering uncertainties from nondestructive examination (NDE) data and fatigue model parameters. The method utilizes uncertainty quantification models for detection, sizing, fatigue model parameters and inputs.

A distribution of the actual flaw size is derived for both NDE data without flaw indications and NDE data with flaw indications by using probabilistic modeling and Bayes theorem. A turbine rotor example with real world NDE inspection data is presented to demonstrate the overall methodology.

Abstract: Method of modelling the evolution of the pH value of a porous medium after injection of an alkaline agent solution into this medium. The alkaline agent is considered as a soda pseudo-constituent of concentration equal to an OH— concentration corresponding to the pH value of the alkaline agent solution injected.

Finally, the evolution of the pH value is modelled by modelling the transport of the alkaline agent solution by means of a soda transport simulator, by replacing the soda by the soda pseudo-constituent.
